Y., A CORPORATION OF DELAWARE PAPER GUIDING- AND GAUGING MEANS Application filed October 15, 1929. Serial No. 399,733.

This invention relates to improvements in typewriting machines and more particularly to paper guiding and gauging means.

An object of the invention is to guide the work sheet vertically between the type carrier or shuttle and the printing hammer so as to present it properly to the types.

In carrying out the invention there is pro-' vided a rack supported on the carriage above the printing means. It is provided with one or more channel shaped guides to hold the worksheet in its vertical position. 4

A scale bar is pivotally supported on the paper rack which may be swung to a position where it may assist in locating the paper guides relatively to the letter space position on the carriage. The scale bar may be swung to another position to serve as an extension of the paper rack.

The `paper rack is Apivotally supported on the carriage so that it may be swung rearwardly to lay the work sheet on an erasing shelf located behind the vertical plane in which the work sheet is fed to and from the printing point. Stops are provided lto limit the movement (if the paper' rack to its various positions where it is held by suitable detents.

The paper rack comprises two vertical end pieces and three horizontal bars connecting said end pieces; the paper guides being supported on the middle one of the horizontal bars and are prevented from rotation about said middle oar by the other two bars.

Other features and advantages will hereinafter appear.

.'Ihe invention is shown as applied to a varlt-yper writing machine which includes a carriage 10 to travel back and forth on a rail 11 secured to the main frame (not shown) the carriage being luided at its upper end by a bar 12, securet? to end pieces 13 of the carriage.

A work sheet 14 may be fed up from a container 15.by feed rollers 16 and 17 to advance it between a printing hammer 18 and a type carrier or shuttle 19. The hammer 18 is arranged behind the work-sheet and is adapted to co-operate with types20 of the type shuttle 19; the shuttle being indexed to select the type in the usual; manner by means including an actuator 21 operated by the character keys, not shown.

To hold the work sheet there isv'provided a paper rack, indicated generally by the numeral 22, which includes two side pieces 23 and 24 secured to each other by horizontal rods or bars 25, 2G and 27. Each one of the side pieces 23 and 24 is supported on a shouldered stud 28, Figs. 1 and 7, secured to the carriage end 13 by a nut 2 9.

Supported on therniddle vbar 26 are two guides 30 and 31 one at each side of the work v vsheet 14. .Each guide has a portion32 bent up from its side edge to form a groove 33 1n which the Work sheetis guided. The

Vvided to hold the paper guide against accidental lateral displacement on the bar. Said spring is located between the two ears 34a and between the back 34 of the paper guide and the rod 36. It is held in place horizontally and vertically by two ears 34nbent..

therefrom and extending into tWo apertures 34d in-the paper guide, Figs. 3 and 4. This arrangement, it will be understood, permits the guide t0 be readily adjusted axially of the supporting bar 26. The upper bar 25 vand the lower bar 27 prevent rotation of the paper guide about the bar'26 or -in other words, hold it in a vertical position.

The web 33a of the paper guide, which joins the portion 32 with the body part 34, is of considerable length and may be used to square a fresh work sheet in the machine. The usual stationary line guides 35 may be used to position a work sheet in the machine at the printing line.

r extension of the paper rack and where it.

An erasing shelf or table 36 is supported on the carriage over which the work sheet may be laid when an erasure is to be made. Said erasing shelf is located behind the plane in which the work sheet is normally disposed. Consequently to lay the work sheet on the erasing shelf the paper rack 22 mayL be swung rearwardly about its pivots 28 to the position in Fig. 6.

AStops 40 and 41 on each of the rack ends 23- and 24 engage a stud 42 on the carriage ends 13 to limit the movement of the paper rack 22 to its active or inactive position, Figs. 5 and 6. To hold the paper rack in either of these positions there is secured to each end thereof a detent spring 44 engaging a corner 45 of rectangular head 46 on the pivot is held against falling rearwardly by fingers bearing against the ends 23 and 24 of the paper rack. The scale bar may be swurigjfrom the position in Fig. 2 to the posiy half of which is twenty-five spaces.

tion in Figs. 1 and 5 in frontl of the work sheet 14, where itl may be arrested by the downward extensions of the backs or body parts 34 of the paper guides, and where it may be used to locate the paper guides in the desired letter space position. The scale 50 may also be usd to position the carriage with reference to a pointer 56 arranged in` the vertical transverse plane ofthe printing point to locate the carriage in any letter space position at the printing point. It may also Y be used to center a'word on the work sheet as follows: Let it be assumed thattlie writing line begins at 5 and terminates at 55 on the scale. This` includes fifty spaces 4the This number of spaces (25) added to'lette'r space at the beginning ofthe line makes 30 which is the center of the writing line. Having once determined the center of the writing line the starting point of any word or group of words may readily be determined by subtracting from this position (30) halfthe number of letter spaces. in the word to be centered on the work sheet.

' The portions 32 of the paper guides are curved rearwardly at their upper ends 52 to direct the work sheet rearwardly towards the scale bar 50 as indicated in Fig. 2. If desired the work sheet may be conducted behind the scale bar.. v

It should be'understood that the paper guides 30 and 31 are formed or bent up from identical blanks 60 like thatfshown in Fig. 8, the ears 34a of the guide 30 being bent from the side edges of the `back portion 34 and in the opposite direction to those on the guide Y 31. Similarly the side members 33 are bent in opposite directions from the back members 34 and the front members 32 are also bent in opposite directions from the side members 33 of the two guides. f It will be understood that irrespective of the position of the scale bar, it is moved back with the paper rack as indicated in Fig. 6 when the latter is swung to its ineffective position. i

Variations may be resorted to withln the scope of the invention.
